Loratadine is the second generation antihistamine, and its main function is anti-allergy. It belongs to tricyclic antihistamines and is regarded as a first-line antiallergic drug because it has no central sedative effect. I suggest you choose loratadine syrup produced by Tianjin Tianwei Pharmaceutical Co., Ltd., and take one tablet every day. The dosage is accurate, the curative effect is good, fast, safe, hygienic and convenient. It can relieve gastrointestinal discomfort.
